Heritage Heating & Cooling

My experience with Heritage Heating & Cooling was a Phenomenal experience!!!

The Staff is very down to Earth, knowledgeable, and is definitely a Company I recommend and will use again!

Larry and Nick are an Awesome duo and I can’t sing them enough praises!

The entire Staffing Team are kind and friendly, from beginning to end!

Definitely a 5 Star Company!

We received multiple quotes for HVAC replacement from local companies and Heritage gave the best price and product. Trent was very kind and knowledgeable during our assessment. Larry and his assistant were kind, knowledgeable, and overall wonderful during the install. We had our old units replaced and the difference we felt was immediate and wish we had done this sooner. If you are debating on whether or not to replace an old system, take the plunge and give Heritage a call.

Very happy with whole experience, from the quote to complete installation. Purchased new HVAC system. Enjoyed installation crew. They were professional, did top notch work, friendly and just good guys!

These guys/gals are on point. I had a heating issue this past winter they fixed quickly. Recently had an AC issue. Called first thing Tuesday morning. A tech was out by 12 that day. Fixed everything quickly. Have a nice military discount. Would 100% recommend.

We had been using another HVAC/heating company for maintenance. We decided to try another company because there was always something wrong with the system that was only 7 years old. We are VERY pleased with the check up that was done - Brian was fantastic! We are only disappointed that we waited so long to try another company. Thank you!

5 stars ⭐️⭐️⭐️⭐️⭐️ for Heritage Heating and Cooling in O’Fallon!

Our AC crapped out and I called Heritage Heating and Cooling to schedule an appointment, I figured they’d be out later this week. They were at my house within the hour. They went above and beyond to help us. Very professional, knowledgeable, kind and no sales pitches or upselling. They just wanted us up and running again. So thankful for such a great local company!! Our service technician, Brian, was very nice and professional. This place is veteran owned and hires veterans to work there.

I highly recommend calling them for any heating or cooling issues!

The entire process from scheduling to repair was much simpler and quicker than I anticipated. The cost was reasonable, as well. Jim was prompt, explained the issue, repaired it quickly. I have absolutely no complaints. Wonderful business.

I would definitely recommend this company. We called them at 8am and made a same day appointment. Our technician arrived a whole half hour before our scheduled appointment. *Which was great*
Our tech Tyler was very professional, knowledgeable and very friendly.

Thank You Heritage and Tyler

I'm updating this review after Jim, the owner of Heritage, reached out in regards to my original comments and 2-star review. I can't simply return and give a raving 5 stars, because that isn't an honest reflection of our experience. But honesty is important to me, and I find myself at half past 2 o'clock in the morning, still trying to find the right words for this review.
I've saved my thoughts in a note for now.

We had an undersized unit in our house and with our son who has trouble controlling his temperature we needed to put in a better fitting system. We compared a few places and chose Heritage. They weren't the cheapest (which was for a less known unit) or most expensive. They were the middle ground price wise with great service and equipment. I am very happy we chose this small local family run buisness. We will continue to use them for matinance once the time comes to start that up. They have a veterans discount as well for those who have served. I am very happy. They just earned themselves (another) loyal customer.
